Hello, I was able to fix the issue with resizing the window when snapped to side.
Also it refers to the bugs
i attached svn patch.
I can confirm that this patch seems to fix all these problems in normal circumstances.
I also found some minor annoyances:
1.) Little visible "flash" when opening new file (Window moves to old location and immediately returns to normal location).
2.) Moving unactivated Np++ window (with programs like Tweakwindow) will cause window to move back to previous location which is annoying.
3.) Sometimes when opening quickly same file (that is opened in Np++) multiple times the window location is forgotten, and window restores to its old position before Auro snap.
I still feel that patch #436 is a better fix for these bugs because it is simpler and it doesn't have these problems.
This bug has been fixed with another patch.
Thank you anyway for the contribution.
